摘　　要：湖上水库坝基下砂卵砾石层中富含大量的块石、漂石,坝基防渗拟采用覆盖层中设置混凝土心墙与基岩中布置防渗帷幕联合方式,运用工程地质分析原理与有限元数值模拟相结合的方法对湖上水库坝基防渗心墙的不同设计深度的渗透性进行分析,确定合理的设计方案并提出可行的施工措施,明确下一步工程实施方向,为工程问题提供了解决思路.The sand and gravel layer under the dam foundation of the Lake Reservoir is rich in a large amount of block stones and boulders.The dam foundation anti-seepage plan is to adopt a combined method of setting a concrete core wall in the covering layer and arranging anti-seepage curtains in the bedrock.This paper combines the principles of engineering geological analysis with finite element numerical simulation to analyze the permeability of the anti-seepage core wall at different design depths of the dam foundation of the Lake Reservoir.It determines a reasonable design plan and proposes feasible construction measures,clarifies the direction of the next stage of project implementation,and provides solutions for engineering problems.
